103 = 1,000
4.5 x 103 = (4.5 x 1,000) = 4,500
45 x 103 = 45 x 1,000 = 45,000
The answer in standard form is: 1,097,509,540,000,000,000,000,000,000,000,000,000,000,000,000
4.5 times 10 to the first power... or just 10 4.5X10
450 ÷ 10 = 45
45 x 10 = 450
45 times
300 million x 45 000 = 1.35 × 10 to the power of 13
45
6 times with a remainder of 10
45 times
4.5 x 10
45 is 10 times larger than 4.5
